Q:92 F150 Fuel tank selector valve?
There is no selector valve on 1992-95 F150's. There were or the older carbureted trucks but newer ones are all fuel injected and have in-tank fuel pumps. The switch on the dash just selects which pump you turn on. I'd say the front tank fuel pump has gone bad or possibly has a cheaper electrical problem (if you're lucky). Exact same thing happened to my 1995 F150. Replacing a pump is a pain and not cheap.
Q:what do the valves of an engine do?
The intake valves allow a air/fuel charge to enter the combustion chamber, the exhaust valves allow it to leave. They need to close and seat properly so when the piston comes up on the compression stroke there is plenty of a compressed air/fuel charge for a strong combustion. Without this compressed charge you will have a little fire in the combustion chamber and not an explosion.
Q:French Horn Valve Compression?
If you like how it plays you might just wish to leave it alone. Anything you do is going to change the way it plays, perhaps to something you don't like. Check compression by pulling the valve slide part way out, wait a second or two and then push the key, as the air fills up the partial vacuum cause by pulling the slide you should hear a nice thunk. If there is no noise when you push the valve the air is leaking around the valve and that's bad compression. Another way to check is just slowly withdraw the valve slide. It should get harder as you pull due to the vacuum, if it comes all the way out it should pop.
Q:Installing kitchen faucet/shut off valves?
You can install a pullout kitchen sink faucet on a wide variety of sinks. There are many options, but the same is not true for the other type of faucet sprayer: A spout sprayer. Let's say you have a old sink to work with. You're probably going to be able to install a pullout sprayer with little problems. You probably won't be able to do the same with a faucet sprayer built in to the spout on an older sink though. These are excellent when you want to spray and wash your vegetables. When you hold your vegetables under a typical faucet, you have to roll them around with your hands in order to loosen any dirt or other contaminants. The sprayer works like a mini hose and can do that work for you.
Q:setting valve lash and proper method?
I truthfully have repaired alot of Chevy engines in my time. I continually adjusted them chilly while i became into development the motor or reinstalling products....much less muss and fuss and much less oil in each single place. The GM instruction manual says ( and that i've got been doing this for years ) is with the engine in the #a million firing place ( it is set via putting your hands on the #1valve because of the fact the mark on the damper comes close to the O mark on the crankcase front conceal. If the valves are actually not shifting then the engine is in the #a million firing place. If the valves flow because of the fact the mark comes as much as the timing tab then it incredibly is in the #6 firing place, and may be became over a million extra time to attain the #a million place.) as basically desperate, right here valves may be adjusted. V8- Exhaust- a million, 3, 4, 8 V8- intake- a million, 2, 5, 7 back out the adjusting nut ( 5/8's socket ) till lash is felt ( flow or spin the push case you could flow it up or down or spin it incredibly is loose ) while play has been bumped off, turn adjusting nut in a million finished turn ( to middle lifter plunger ) Use basically slightly chalk to mark which valves you have adjusted to maintain music ...desire I helped and sorry for the long dissertation.
Q:pool and spa valve diagrams?
You have one or more faulty valves or you've got them turned the wrong way for the operation you want. You also may have a check valve that's going bad. The problem is that I'd have to see the setup around the pump and filter to even get an idea of what goes where. My pool has electric activators for the valves that allow automatic operation from inside the house. I adjusted one incorrectly once and it activated the valve backwards, and I had to readjust it.
Q:Flap valve replacement?
pricey Vongirl, Congratulations on the lengthy lasting heart valve. frequently mechanical valves do not very last somewhat that lengthy. Mechanical, bovine, porcine and donor valves all positioned on out. It in basic terms relies upon on the timing. i'd say two decades with an same valve is somewhat magnificent. i wish, once you get your replace it lasts two decades besides!!!
Q:Need help finding a specific valve...?
The leading maker of solenoid valves is ASCO. Their website is shown below. If a valve that fits your application exists they probably make one. If you can't find a suitable solenoid then you need to consider a pneumatic valve operated by a solenoid valve. That is a common solution for a problem like yours. As to the male connections. If they are not available then you can just use a pair of threaded fittings (pipe nipples) to change the configuration.
Q:Using thicker oil to eliminate valve clatter?
I wouldn't go any thicker than 10w-40. I have seen 20w-50 in the parts stores, but this will put a lot of strain on the oil pump. You may regret it down the road, and it's just a little bit of noise. Good luck.
Q:Having difficulty putting valve rocker back on pushrods and valves...?
Panic? run around in circles? I have no thought what you prefer to do. yet in case you have been thinking, wanna comprehend how a lot of those little plastic rings that protection seal the bottle caps to the oil bottles i've got discovered under the valve cover? we could basically say lots, did they harm something? no, they only take a seat there, as there too great to pass down the oil galley and in the event that they have been that they had take a seat interior the backside of the oil pan or get caught to the oil pump %. up show screen, i'd desire to pass on approximately issues i've got discovered sitting in oil pans and caught to the show screen yet I wont, yet little products of RTV are on the ideal of the record, and if the show screen misses it your oil filter out won't.
